Limestone (CaCO $_{3} )$ reacts with hydrochloric acid according to the equation $\mathrm{CaCO}_{3}+2 \mathrm{HCl} \rightarrow \mathrm{CaCl}_{2}+\mathrm{H}_{2} \mathrm{O}+$ $\mathrm{CO}_{2}$ . If 1.00 $\mathrm{mol}$ of $\mathrm{CO}_{2}$ has a volume of 22.4 $\mathrm{L}$ under the reaction conditions, how many liters of gas can be formed by reaction of 2.35 $\mathrm{g}$ of $\mathrm{CaCO}_{3}$ with 2.35 $\mathrm{g}$ of $\mathrm{HCl}$ ? Which reactant is limiting?

Key Concepts

Molar Volume of a Gas

Molar volume is the volume occupied by one mole of a gas under specified conditions, such as standard temperature and pressure. This concept allows one to convert the number of moles of a gaseous product into a volume, facilitating the comparison between theoretical and experimental quantities.

Mole Concept and Molar Mass

The mole concept is central to chemistry as it connects the mass of a substance to the number of particles it contains using its molar mass. By dividing the given mass of a substance by its molar mass, one can calculate the number of moles, which is crucial for stoichiometric calculations.

Limiting Reactant

The limiting reactant is the substance in a chemical reaction that is entirely consumed first, thereby determining the maximum amount of product that can be formed. Identifying the limiting reactant is essential in predicting the final yield of the reaction.

Stoichiometry

Stoichiometry involves calculating the relationships between reactants and products in a chemical reaction according to the balanced chemical equation. It allows one to convert between the masses, moles, and volumes of substances, ensuring that the proportional relationships implied by the equation are maintained.
